ARPA-E awards U-M $1.9M to develop advanced low-cost high-efficiency engine; boosting, highly dilute combustion and 48V system

Green Car Congress

million to a project to develop a high-efficiency engine system that integrates a compact micro-hybrid configuration of a supercharger with an electric waste heat recovery system and employs high rates of recirculated exhaust gases. If we improve the responsiveness of small engines, then we can push for more efficient cars at low cost.

Downsized 4.0 TFSI for Audi S8 cuts fuel consumption 23% compared to predecessor; cylinder deactivation and start-stop

Green Car Congress

Audi’s principle of downsizing: “ Forced induction replaces displacement ” One twin-scroll turbocharger per cylinder bank compresses the fresh air. From each pair of cylinders, the exhaust ports lead separately to a manifold and the turbocharger housing; they are not combined until immediately ahead of the turbine.
